[TPIN] BACH 37

Richard,
An interesting theory that I hadn't thought of. It would kind of
increase the anxiety level on those slow, "Pretty", long winded, solos.

I think it's more likely that the valve doesn't stay in the "down"
position for more than an instant unless it's being played. That's
possibly why the problem seems to correlate with the horn being played. 

If something is out of alignment, more than a second or two in the down
position will give the oil film a chance to break down and cause
metal-to-metal contact. Thus, with only the spring force to return the
valve, it may stick.

I don't know why this would only happen when you are blowing air through
the horn unless it was temperature related and binding as your horn
warms up.
